The old saying about land is true, “They aren’t making any more of it.” It has value. It could be sold off not to people/companies looking to build but to create new cities. This would free it from the corruption of Detroit’s government and the hindrance of its taxes/regulation.
This is painfully naive. The land has no value precisely because of the people who live there and those who govern it.
Going into the not too distant future there will not be a need for so much land due to the worldwide drop in fertility rates.
There is plenty of land to be had in better governed jurisdictions.
I just read Detroit is about to demolish 4,000 structures.
That only leaves about 66,000 empty buildings and homes.
It would be interesting to see Detroit divided into several "towns". The towns could try different solutions to their various problems to see what works and what doesn't. It could be a learning opportunity for other communities that are about to follow Detroit over the cliff.
